The Input voltage detection type can be used as the voltage supervisor of microprocessor system like the following circuit. In this case, a detection power supply voltage is approximately 1.25 x (R1+R2)/ R2 (v). The detecting supply voltage can be set between 2V and 10V. Note 2. The detecting voltage can be adjusted by changing R1 and/or R2 in the following circuit. The detection accuracy is ±4%. Note 3. It has a delay capacitor and the delay time is about 200µs.

A delay time of the supply voltage detection type can be set to one among 25ms, 50ms, 100ms and 200ms by the combination of pin 1 and pin 3. Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire or property damage. Remember to give due consideration to safety when making your circuit design,in order to prevent fires from spreading, redundancy, malfunction or other mishap.
